  • Industrial-grade material certification conforming to ASTM A106, A53, and A733 specifications

Professional Applications & Engineering Value

This heavy-duty black-coated steel threaded pipe nipple delivers critical performance in demanding industrial settings where pressure integrity and corrosion resistance are paramount. The seamless construction combined with Schedule 160 wall thickness (0.343") provides exceptional burst strength for high-pressure hydraulic systems, steam lines, and natural gas applications. The NPT threaded connections ensure secure, leak-resistant joints in 3000-class steel fittings and 1500-class flange systems, while the protective black coating significantly extends service life in corrosive environments. Engineered to handle multiple media types including oil, water, and compressed air, this 2" pipe nipple represents a reliable solution for maintenance and new installations across processing plants, manufacturing facilities, and energy infrastructure.

Specification Summary & Compliance

This 2" NPT threaded pipe nipple features precision ASME B1.20.1 tapered pipe threads with industrial-grade dimensional tolerances. Manufactured from certified steel materials meeting ASTM A106, ASTM A53, and ASTM A733 specifications, the component carries full REACH (EC 1907/2006) and RoHS 3 (2015/863/EU) compliance. With 2" pipe size (Dash 32), 3" length, and 0.343" wall thickness, this Schedule 160 pipe nipple delivers consistent performance across its rated pressure applications.
